What layers do you see in the application? How do they communicate?

Answer from AI

In a typical application, several layers can be distinguished:

  1. Presentation Layer (UI/Frontend) — interacts with the user, displays data, and accepts input.
  2. Business Logic Layer (Backend) — implements the rules and processes of the application.
  3. Data Access Layer (DAL) — responsible for interacting with the database or other storage.

Communication between layers usually occurs through well-defined interfaces or APIs. For example:

  • The UI calls business logic methods via REST API or RPC.
  • Business logic interacts with DAL through abstractions that hide storage details.

This separation facilitates maintenance, testing, and scaling of the application.
